Hello, I’m posting this today because I’ve been on this model for a long time and I can’t get it to fire properly or it doesn’t work. I’d like to know if anyone here has done this model before and could help me please. This is one of my favorite models and I can’t seem to get it to work. Thanks to anyone who can help me
So, from my experience with the NaG (I’ve built 3, 2 have exploded)…
Issues with loading/firing/extracting are usually down to the chamber geometry. You need to sand or file a slight cone into the chamber (for extraction) and a “feed ramp” into the top and bottom of the breech end of the chamber (for feeding).
I used rifled barrel liner for all my builds. The scuttlebutt is that a smooth 6mm ID 8mm OD stainless pipe will work better, because it produces less back pressure.
The best way to taper the chamber seems to be chucking the barrel into a drill and wrapping a piece of sand paper over a small rod, held at an angle, while the barrel spins.
I have a video on my odd sea firing the NaG https://odysee.com/@FieldExpedient:6/NaG01:e
